Water deteriorates lubricating oils: removal of water in lubricating oils using a robust superhydrophobic membrane

Nanoscale, 2020
Lubricating oil failure caused by water is solved by a robust membrane that shows steady performance in regard to extreme water repellency, high-efficiency purification of lubricating oils, and low wear volume even after harsh mechanical damage.

Used lubricating oil recycling using hydrocarbon solvents

Journal of Environmental Management, 2005
A solvent extraction process using new hydrocarbon solvents was employed to treat used lubricant oil. The solvents used were liquefied petroleum gas (LPG) condensate and stabilized condensate. A demulsifier was used to enhance the treatment process. The extraction process using stabilized condensate demonstrated characteristics that make it competitive

The Research on Oil-Air Lubrication and Oil Lubrication Used in the Sliding Friction Element

Key Engineering Materials, 2011
In order to study the effect of oil-air lubrication on sliding friction element, the experiments between oil-air lubrication and oil lubrication have been done by using friction-abrasion testing machine. By means of measuring the temperature rise, the friction coefficient of two different lubrication systems in the same conditions and studying the ...

Asphalt modification with used lubricating oil

Canadian Journal of Civil Engineering, 2008
The viability of used lubricating oil as an asphalt modifier was studied, with the enhancement of the low-temperature grade as the specific goal. Used oil modification was found to improve the Superpave low-temperature performance grade (PG), but at the expense of the high-temperature PG grade.

CATALYTIC UPGRADING OF USED LUBRICATING OILS

Fuel Science and Technology International, 1986
ABSTRACT Several commercial catalysts were tested for their activity for upgrading waste lubricating oils. The feedstock was vacuum distilled to remove the light and the heavy ends. Two trickle-bed reactors placed in series were employed, the top reactor contained a high surface area alumina and the bottom reactor the catalyst.

The lubricating properties of used engine oil

Wear, 1982
Abstract The lubricating properties of oil samples from four cars using either leaded or unleaded gasolene were examined using a cross-pin-type lubricant tester and a JIS four-ball tester. The zinc dialkyldithiophosphate (ZnDTP) content in the oil samples was determined by thin layer chromatography (TLC). The wear scar diameter increased with running
